An extract from Kallos' Thesis Abstract:

As...plasma acceleration technologies mature, one of the main future challenges is to mono-energetically accelerate a second trailing bunch by multiplying its energy in an efficient manner...The work presented here analyzes the use of multiple electron bunches in order to enhance certain plasma acceleration schemes. Specifically, the acceleration of a trailing electron bunch in a high-gradient wakefield driven by a preceding bunch is demonstrated experimentally for the first time... Additionally, it is found ... that by using multiple bunches to drive the wakefields, the energy of a trailing bunch could be efficiently multiplied in a single stage, thus possibly reducing the total length of the accelerator to a more manageable scale.

Kallos performed this research at the Electrical Engineering Department of the University of Southern California in Los Angeles under the supervision of Thomas Katsouleas.

Presently Kallos is a researcher at Queen Mary University of London, England.
